FD820 Rotary Drilling Rig
FD820 rotary drilling rig is the extension of small torque drilling equipment series of our company. This product is specially designed for special working environments such as high-voltage power lines, bridge constructions and tunnels.
This model is the first tunnel drilling machine available in China. Our versatile deep foundation machine is endowed with torque of 80kN.m, overall height of 7.3m and drilling depth of 20m. Moreover, custom services are offered to proffer more well-suited solution to your unique application needs.
Advantage
1. Cost containment
This rotary drilling rig is fitted with folding mast and patented drill head structure, delivering impressive cost effectiveness and durability as well as easy and low maintenance.
2. Ensured safety
Thanks to guide frame mounted on the top, remarkable verticality between drill rod and ground is maintained, resulting in impressive operation safety.
3. High efficiency
Main winch adopts hydraulic motor imported from Italy, offering fast response and free fall. Working speed reaches 80m/min, thereby working efficiency is drastically promoted. Furthermore, the main winch of this rotary drilling rig is placed in the front of operative's right side, which enables the operative to watch the working condition the all time and avoid winding failure.
